IP LUMB-IBOIB-POINT PROTECTOR AND CORD-HOLDER.

' Specification of LettersPatent.

Application filed December 2, 1914. Serial No. 875,096.

To all whom it may concern:

Be it known that I, DAVID, R. BYRON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful. Improvements inPlumb Bob Point Protectors and Cord- Holders, of which the followingis aspecification.

My invention relates to improvements in plumb bob point protector.and'cordholder, the object of the invention being to provide anattachment which is positioned over the pointed end of the plumb bob tothoroughly protect the point, and adapted to receive the cord woundabout thesanie. and about the plumb bob, and securely hold the cord fromunwinding. I

Heretofore, it has been the practice for carpenters and others to wrapthe cord around the plumb bob and throw the same into the box orreceptacle containing other tools. In the course of time, the cordbecomes more or less unwound and tangles about other tools in the box aswell as causing the thread to become knotted and troublesome to use.

It is the purpose of my invention to permit the cord to be so securelywound about the plumb bob that it cannot work loose, and hence theobjections above noted are entirely overcome and the cord can be readilyunwound and will be ready for instant use whenever desired.

A further object is to provide an attachment of the character statedwhich is adapted for use on any style of plumb bob, and which may bemanufactured and sold at an extremely low price.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in side elevationillustrating my improved attachment in operative position on the end ofthe plumb bob. Fig. 2 is a fragmentary view in longitudinal section.Fig. 3 is a view similar to Fig. 2 showing the attachment in section atright angles to Fig. 2, and Fig. 4: is a perspective view of my improvedattachment.

1 represents a plumb bob having a pointed end 2, and at its oppositeendprovided with a neck 3 having a head 4 at its free end.

5 is the cord projecting from the center of the head 4, and of thenecessarylength for ordinary use.

My improved attachment6 constitutes 'a metal casting having a conicalbore 7 to receive the pointed end 2 of the plumb bob. The casting 6,attwo opposite sides, tapers toward its outer end as shown at 8, and isprovided in its extreme outer end with an opening9, so that dirt whichcollects in the attachment can be forced through the opening. The othersides 10 of the attachment are slightly tapered, and in the extremeouter end of the casting, Iprovide two cord receiving recesses 11, thewalls of which are adapted to grip and hold-the cord;

12, 12 represent arms integral with the attachment at its wider end, andprojecting in opposite directions. These arms 12 have their outer faces.recessed as shown at 13 to receive the cord, and, prevent the latterfrom slipping off the ends of the arms.

While my invention is, of course, not limited to any particular mannerof winding the cord, I have illustrated in- Fig. 1 an extremelyefiicient, method of doing so. In this view, it willbe noted that thecord 5 is extended longitudinally of the plumb bob as shown at 14, overone arm 12 of the attachment 6. The cord then extends back to the neckportion 3 and is wound around the latter as shown at 15. The cord thenextends along the opposite side of the plumb bob as shown at 17 andaround the other arm 12 of the attachment 6. The cord then extends backto the neck portion 5 and is'again wound around the same, and ifdesired, several of these longitudinal runs of the cord may be hadaround the arms 12 and the neck portion 15 in accordance with the lengthof the cord.

Nhen the cord has been positioned around the arms,it is then woundaround the smaller end of the plumb bob adjacent the attachment as shownat 18. This last-named winding causes the longitudinal runs ofv the cordto be drawn in tightly against the plumb bob, and take up any slack inthe cord as well as compel the attachment to be drawn tightly on the endof the plumb bob. After this winding 18, the cord is passed around thearms 12 and through the cord holding recesses 11 in the end of theattach- Patented July 20, 1915.

ment. The walls of these recesses 11 serve as gripping surfaces tofirmly hold the cord and prevent the same from unwinding.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An attachment of the character stated, comprising a hollow bodyadapted to receive the pointed end of a plumb bob, and said body havinglaterally projecting cord receiving arms thereon, substantially asdescribed.

2. An attachment of the character stated, comprising a hollow bodyadapted to receive the pointed end of a plumb bob, said body havingintegral laterally projecting cordreceiving arms at its opposite sides,substantially as described.

8. An attachment of the character stated, comprising a hollow bodyadapted to receive the pointed end of a plumb bob, said body havingintegral laterally projecting cordreceiving arms at its opposite sides,and said body having cord-receiving recesses in its outer end,substantially as described.

4. The combination with a plumb bob having a pointed end, and anintegral neck at it opposite end with an enlarged head at the outer endof the neck, and a cord secured at one end to said head, of anattachment constituting a hollow body positioned on the pointed end ofthe plumb bob, the said cord wound about the plumb bob, and the saidattachment, the latter having means thereon for holding the end of thecord against movement, substantially as described. v

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DAVID R. BYRON.
